Abstract:
An object is to provide a method for making it possible to exchange information between a local host and a remote host even if necessary software is not previously prepared. A local host (1) requests a service administration host (4) to start a desired remote service. In response to the request to start the remote service, the service administration host (4) selects remote hosts (2) that are capable of sharing the remote service with the local host, and returns information as to the remote hosts (2) to the local host. Based on the returned information as to the remote hosts (2), the local host (1) selects a remote host (2) with which it desires to share the remote service, and instructs the remote host (2) to download, from the service administration host (4), software for sharing the remote service. The remote host (2) downloads, from the service administration host (4), necessary software as instructed.
Abstract:
A brake apparatus for a cycle designed so that a toe-in angle of a brake shoe can be set with ease and with high accuracy when the apparatus is assembled. When a toe-in setting member between the brake shoe and a clamping mechanism is deformed, a difference is produced between the angle at which a brake shoe is attached to a support member before the deformation and the angle at which the brake shoe is attached to the support member after deformation. The extent to which the toe-in setting member is deformable has previously been set so that the difference in angle will become a predetermined toe-in angle. A clamping mechanism is operated to clamp the brake shoe to the support member such that the brake shoe can be pressed against a wheel rim. Consequently, when the brake is operated, the brake shoe contacts the friction surface of the wheel rim with a predetermined toe-in angle.

An Escherichia bacterium having dihydrodipicolinate synthase and aspartokinase, both of which are desensitized to feedback inhibition by L-lysine. The intracellular activity of dihydrodipicolinate reductase in this bacterium can also be enhanced. Furthermore, a diaminopimelate dehydrogenase gene can be introduced into this bacterium, or intracellular activities of tetrahydrodipicolinate succinylase and succinyl diaminopimelate deacylase can be enhanced. Finally, the intracellular activities of aspartate-semialdehyde dehydrogenase or phosphoenolpyruvate carboxylase can be enhanced in this bacterium. The bacterium can be cultured in a suitable medium to produce and accumulate L-lysine in culture, and the L-lysine is collected from the culture.
